I thought there were quite a few that I didn't consider upsets. I realize he had to stretch to get 45 we would recognize but, about half way through I thought to myself, these aren't upsets they're fights.
One beautiful one he missed (or did I?) was Sakuraba/Conan Silvera at UFC Japan. Saku was totally unknown (outside of Japan) and looked like a school boy. Conan was Brazilian, champ of xyz fighting, and looked like ....Conan.
Also, While Serra/GSP was the most exciting one to me at the time, I think it's an insult to Matt to call it #1 ever. Matt hits HAAAHD and has the most under rated/ under used BJJ in the game.
Fun to read at 4am ...thanks
